Agricultural Water Conservancy Facility Preservation and Repair Method "Water Stop Band Method"

Repair and seismic reinforcement of pipeline joints! Repair methods to prevent the decline of water stop performance.

The "Water Stop Band Method" is a repair technique that uses water-expandable sponge within the water-tight rubber of the water stop section to prevent the decline in water stop performance caused by the compression permanent deformation of the water-tight rubber. The water-expandable sponge attached to the water stop section of the water-tight rubber enhances the water stop effect due to the lateral restraint force at both ends of the attachment groove. Additionally, by making the bolt fixing part after the expansion of the fixed ring in a wedge shape, it creates a structure that prevents loosening. 【Features】 ■ Repair and seismic reinforcement method for pipeline joints ■ Prevents decline in water stop performance ■ Uses water-expandable sponge ■ Loosening prevention structure ■ Design registration No. 1400834 *For more details, please refer to the PDF document or feel free to contact us.
